Uncoupling of oxidative phosphorylation

3 Uncoupling by picrate A comparison ofthe binding and uncoupling properties of picrate (2,4,6-trinitrophenol) with those of other uncouplers such as NPA and 2,4-dinitrophenol is probably ofcrucial importance for the understanding of the mechanism of uncoupling and of oxidative phosphorylation. Martineau L (2012) Large enhancement of skeletal muscle cell glucose uptake and suppression of hepatocyte glucose-6-phosphatase activity by weak uncouplers of oxidative phosphorylation, Biochimica et Biophysica Acta (BBA) - General Subjects, 10.1016/j.bbagen.2011.11.012, 1820:2, (133-150), Online publication date: 1-Feb-2012. Uncoupling of oxidative phosphorylation enables Candida albicans to resist killing by phagocytes and persist in tissue. Cheng S(1), Clancy CJ, Zhang Z, Hao B, Wang W, Iczkowski KA, Pfaller MA, Nguyen MH. Author information: (1)The University of Florida College of Medicine, Gainesville, FL, USA. Biochemistry All Publications/Website. OR SEARCH CITATIONS The oxidative phosphorylation system is localized in the inner mitochondrial membrane. Uncoupling agents allow electron transport to oxygen to continue but prevent the phosphorylation of ADP to ATP, that is, they uncouple the energy-yielding from the energy-saving process. The regulated uncoupling of oxidative phosphorylation is a biologically useful means of generating heat.

Uncoupling of oxidative phosphorylation Walter G. Hanstein The mechanism of oxidative phosphorylation is one of the most important problems in classical biochemistry, which has defied a solution for over thirty years. Uncouplers are powerful tools in the study of the coupling between oxidation and phosphorylation, and

uncouplers of oxidative phosphorylation - YouTube Uncouplers of oxidative phosphorylation in mitochondria inhibit the coupling between the electron transport and phosphorylation reactions and thus Uncoupling of oxidative phosphorylation enables Candida albicans to resist killing by phagocytes and persist in tissue Shaoji Cheng,1‡ Cornelius J. Clancy,1,2‡ Zongde Zhang,1† Binghua Hao,1 Wei Wang,1 Kenneth A. Iczkowski,1,2 Michael A. Pfaller3 and M. Hong Nguyen1,2* 1The University of Florida College of Medicine and 2The The oxidative phosphorylation system is localized in the inner mitochondrial membrane. Uncoupling agents allow electron transport to oxygen to continue but prevent the phosphorylation of ADP to ATP, that is, they uncouple the energy-yielding from the energy-saving process. The dissociation or “uncoupling of phosphorylation from electron transport by 2,4-dinitrophenol was first described by Loomis and Lipmann in 1948 (1). Since then 2,4-dinitrophenol has been regarded as the classic uncoupler of oxidative phos- phorylation.

Uncouplers of oxidative phosphorylation in mitochondria inhibit the coupling between the electron transport and phosphorylation reactions and thus inhibit ATP synthesis without affecting the respiratory chain and ATP synthase (H(+)-ATPase). Miscellaneous compounds are known to be uncouplers, but wea …

Therefore, 2,4-dinitrophenol will: A) allow electron transfer in the presence of oligomycin. B) allow oxidative phosphorylation in the presence of oligomycin.
